Trust me you're not the only one

We think that harry potter was the only chosen one but what if he wasnt? Introducing Caitlin le fey the descendant of the great Morgana le fey. Her parents were killed the same night as harry's and so was her brother Morgan. She has the scar as well but on her neck. She is adopted by her muggle cousin and taken care of but she doesn't know she is a witch. Until she gets a letter from a owl and meets a boy who is the same as her 'a chosen one'
